Sort array of dates with date month and year in objective c

Question

I want to sort an array with a date but the date has only sort with date and month, and not sorting with year my code:

NSArray *sortedArray = [arrClassSehedule sortedArrayUsingComparator:^NSComparisonResult(NSDictionary *obj1, NSDictionary *obj2) {
    NSDate *d1 = [appSharedData.CommanFormatForConditional dateFromString: [obj1 objectForKey:@"scheduleStart"]];
    NSDate *d2 = [appSharedData.CommanFormatForConditional dateFromString: [obj1 objectForKey:@"scheduleStart"]];
    return [d1 compare: d2];
}];

It's not sorting properly by date.

Answer 1

It seems like a typo.

Please replace the code with

 NSDate *d2 = [appSharedData.CommanFormatForConditional dateFromString: [obj2 objectForKey:@"scheduleStart"]];
